Include names of students from the user, terminated by ZZZ, and

create a data file GRADES with records of the form:
student (string), test1 (integer), test2 (integer), test3 (integer)
In this file, all test scores should be set equal to 0.

To create a data file named GRADES with records of the form (student, test1, test2, test3), where all test scores are set to 0, you can follow these steps:

Step 1: Collect the student names from the user terminated by "ZZZ".
Step 2: Open a file named "GRADES" in write mode.
Step 3: Iterate over the collected student names and write each record to the GRADES file with test scores set to 0.
Step 4: Close the GRADES file.

Here is an example code in Python to achieve this:

```python
# Step 1: Collect student names from the user
students = []
while True:
student_name = input("Enter student name (or ZZZ to finish): ")
if student_name == "ZZZ":
break
students.append(student_name)

# Step 2: Open GRADES file in write mode
with open("GRADES.txt", "w") as file:
# Step 3: Write records to the GRADES file with test scores set to 0
for student in students:
file.write(f"{student}, 0, 0, 0\n")

# Step 4: Close the GRADES file
file.close()
```

In this code, we first collect student names from the user terminated by typing "ZZZ". Then, we open the file named "GRADES.txt" in write mode using the `open()` function. We iterate over the collected student names and write each record to the file using a for loop. Each record consists of a student name followed by test1, test2, and test3 scores set to 0. Finally, we close the file using the `close()` method.
